Used this on my 2008 Mazdaspeed 3 and it make short work of replacing the rear trailing arm bushings. I uses this with the Mevotech MS40403 bushings and had no issues. The tools seems well built and did not flex during use. If you don't have any air tools that is ok, I used a 24mm socket and a 3/8" ratchet handle.The cups fit the bushings well and you just need to be careful to line things up so the bushing goes in straight. the tool comes with basic instructions and it is intuitive to use.Local dealer wanted $280 to press out and press in a new bushing....just for labor...save yourself and buy this instead!This thing is legit. It's easy to work with. Believe or not it's cheaper than taking the car to the dealer.fast shipping and great price
